(1) If the production efficiency of metal stretching and stamping processing is high and the operation is simple, large companies will develop robots for mass production and automation. Ordinary stamping machines can punch dozens or hundreds of times per minute, while high-speed stamping machines can punch hundreds of times per minute, producing one stamped part per punch.

(2) Just like using two peas to ensure the surface quality of stamped parts, the mold life is usually longer. The stamping quality is stable, the interchangeability is good, and it has the same characteristics.

(3) Stamping can process parts with a wide range of sizes and complex shapes, such as clocks, stopwatches, car longitudinal beams, panels, etc. This material has cold deformation and hardening effects during the stamping process, with high stamping strength and hardness.

(4) Sometimes stamping does not produce chips and debris, uses less material, and does not require other heating equipment. So this is a material saving and energy-saving processing method, and the cost of stamping parts is lower.

The production process of metal stretching and stamping parts is divided into the following parts: 1. Raw materials; 2. Mold; 3. Punch press.

1. There are various main materials for stamping, and stainless steel is one of the widely used ones. When using stamping machine equipment, stainless steel is processed into the shape and size designed for stamping products through molds. Most stamping products are made of steel plate materials through stamping molds. Metal stretching and stamping products are ubiquitous in our lives, including metal stretching accessories; Hardware stretching and stamping parts for household appliances; Household kitchen daily necessities; Automotive hardware stretching stamping parts, body, chassis, automotive boosters, automotive brake pads, radiators, etc. are all made through stamping. The requirements for stamping materials are very high, such as hardness, strength, tensile performance, corrosion resistance, surface quality, and plasticity. The specific thickness is currently under consideration.

2. With the rapid development of the industry and the increasing variety of stamping products, mold design has become increasingly precise and complex. The qualification rate of stamping products is closely related to the rationality of stamping die design. The shape and surface quality, dimensional tolerances, and product qualification rate of stamped products are all related to the process structure design of the mold. Technically more reasonable, in short, it is usually a single process mold. If product processing is allowed, multi process or progressive molds or composite molds can be used.

3. Hardware stretching and stamping equipment is a commonly used hydraulic press in factories. Punching machines are divided into ordinary presses and high-speed presses. Usually, if the process allows, they mostly use high-speed punching machines or multi process hydraulic presses. The key factors for producing qualified products are advanced stamping equipment and mold technology.

What are the stamping processes and processing techniques for metal casings? Hard shells have become raw materials due to their characteristics of easy stamping, high flexibility, and high levelness, and are therefore widely used in various industries. The processing of precision metal stretching and stamping parts will introduce the stamping and deep drawing processing technology of aluminum alloy shells.

1. Internal high-pressure forming technology

IHPF is an emerging molding technology that has only emerged in recent years and is at the forefront of international research. According to their structural characteristics, various connectors can be formed through internal high-pressure molding or ordinary extrusion methods. Then it can be calibrated through internal high-pressure molding. The tube blank is formed by being pressed into the mold cavity through internal pressure and axial force. Due to its excellent performance and high degree of design freedom, internal high-pressure formed parts can replace welded parts, thereby avoiding deformation and deformation caused by welding, and having high dimensional accuracy and mechanical performance. The main advantage of this system is to reduce mass and save materials.

2. Precision aluminum die-casting technology and stamping technology commonly used in automobiles

Most aluminum alloy frame joints are formed by casting. Mainly using advanced high-precision die-casting methods, such as semi-solid die-casting. The semi-solid die casting technology has two forming processes: rheology and thixotropy. The former involves feeding liquid metal into the cylinder of a specially designed die-casting machine, and then cooling it into a semi-solid slurry through a shearing screw device before die-casting. The latter involves sending solid metal particles or fragments to a screw injection molding machine, where they are heated and sheared to convert into a slurry.
